T0 cil/ZZ when?, t imag cm1/cern:

Be it known that I, PATRICK J. FOLEY, a citizen of the United States, and residing at Jersey City, in the county o'l Hudson and State of New Jersey, have invented certain new and useful Improvements in Heating Attachments -for Gas-Burners, of which the following is a specilication such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to heating attachments for gas-burners 5 and the object thereof is to provide an improved device of this class which is designed to be connected with an ordinary gas-burner having an ordinary burner-tip and which may be applied for use without changing the tip and detached therefrom, so that the tip may be used as an ordinary illuminating-burner .whenever necessary.

The invention is hilly disclosed in the following specification, ot which the accompanying drawings form a part, in which the separate parts et my improvement are designated by suitable reference characters in each of the views, and in which- Figure l is a sectional side view of an ordinary gas-iitting provided with the usual burner tube and tip and showing my improved heating attachment connected therewith, all of said parts being in section 3 Fig. 2, a transverse section on the line 2 2 or Fig. 1, and Fig. 3 a side view of the burner attachment.

In the drawings forming part of this speciication, l have shown an ordinary gas-'EX- ture comprising a tube a, provided at one end with a coupling a?, with which is connected an ordinary illuminating-burner t, provided with a burner-tip t2, and in the practice o'l" my invention l provide a heating attachment comprising an open-work plate or support c, having a central depending tubular member or sleeve c2, adapted to be slid onto the gas-burner tube b. rl\he open-work plate or support c comprises, in the form of construction shown, a rim c3 and radial arms c4; but this support may be made in any desired manner. 'l` he sleeve c2 is provided just below the support c with radial ports er passages c5, three oi which aie shown, and beltw these and centrally of the tube cr sleeve c2 said tube or sleeve is provided with oblong side openings c, and mounted on said tube or sleeve is an adjustable sleeve member d by which the size of the slots or openings ci may be regulated. When constructed this manner, the tube or sleeve c2 of the support,

c serves as an ordinary Bunsen burner, and

in practice the ygas escapes through the burner-tip b2, and air entering through the,

side openings c mingles therewith, and the gas and air thus mingled escapes through the ports or passages c5 and is burned in a circle around and beneath the support C.

Any suitable vessel may be placed on the support c for heating water, milk, or any other material, and when the said vessel is placed on the support c the cent-ral bore or passage through the tube or sleeve c2 of said support, which is normally open, is practically closed by said vessel, and very little, if any, gas will escape, except through the ports or passages c5; but it any gas should escape at the opening c7 it vv ill be deiected by the bottom of the vessel and w ill ignite and burn together ith the gas escaping through theV ports or passages ci.

rl'he central bore or passage through the tube or sleeve c2 of the support c is made open at both ends in order to facilitate casting of the support g but the said bore or passage where 1t passes through the support c may be closed7 if desired.

ln the construction shown the upper end of the burner-tube b is slightly smaller in diameter than the inner diameter. of the tube or sleeve c2, and this forms an annular chamber or space around the upper end of the burner-tube, as shown at e, which facilitates'the mingling of the air which enters through the sice ports or passages c6 with the gas escaping Jfrom the tip b.

'.l'his device is simple in construction and operation and may be applied to ordinary illuminating-gas burners whenever desired and may be detached therefrom whenever necessary, in which last event the burner may be used as an ordinary gas-burner.

Having fully described my invention, what l claim as new, and desire to secure by Letters Patent, is-

l. A heating attachment for illuminatinggas burners, comprising an open-work plate forming a support and provided with a central depending tubular sleeve adapted to be slipped onto the burner-tube so as to inclose said tube and the burner-tip, said tubular sleeve being greater in diameter than the top portion of the burner-tube forming therebetween a space and being provided adjacent to the plate with radially-arranged IIO ports or passages7 and beloW said ports or ports or passages, and below said ports or l passages with vertically-arranged slots or openings leading to said space, and an adjustable sleeve mounted on said tubular sleeve and adapted to regulate the size of said slots or openings.

In testimony that I claim the 'foregoing as my invention I have signed my name, in presence of the subscribing Witnesses, this 20th day of January, 1906.

PATRICK J. FOLEY.
